A method for catalytic oxidizing conversion of combustible carbonaceous matter into synthesis gas using a partial oxidation (POX) method is characterized by oxidation of said carbonaceous matter, which is in gaseous, vapor, or ash-free form, with an oxidizing agent in the presence of two consecutive POX catalysts supported on layered carriers. The first layer catalyst consists of a mixture of nickel and cerium oxides with a weight ratio of Ki/Ce ranging from 0.5:1.0 to 1.0:1.0, exhibiting oxidizing properties towards said matter at temperatures ranging from 1200 to 800° C. The second layer catalyst comprises metallic nickel or a mixture of nickel and cerium oxides with a weight ratio of Ni/Ce ranging from 2.0:I:0 to 10.0:1.0, demonstrating reduction-recombinatory properties at temperatures ranging from 800 to 300° C.
A method for catalytic oxygenation conversion of carbonaceous combustible matter into synthesis gas using a partial oxidation (POX) method, characterized in that said carbonaceous matter in gaseous, vapor, or ash-free liquid form is oxygenated by an oxygenating agent in the presence of two consecutive POX catalysts supported on layered carriers. The first layer catalyst consists of a mixture of nickel and cerium oxides with a weight ratio of Ni/Ce ranging from 0.5:1.0 to 1.0:1.0, exhibiting oxidizing properties towards said matter at temperatures ranging from 1200 to 800° C. The second catalyst layer comprises metallic nickel or a mixture of nickel and cerium oxides with a weight ratio of Ni/Ce ranging from 2.0:1:0 to 10.0:1.0, demonstrating reduction-recombinatory properties at temperatures ranging from 800 to 300° C. The temperatures within the layers of these catalysts gradually change along the direction of the inflowing feedstock from a maximum of 1200° C. upon contact with the first layer to a minimum of 300° C. at the outlet of the synthesis gas, which is the product of this conversion. The temperature of the first, initially cold catalyst layer during cold start-up is raised to at least 750° C. using a gliding electrical discharge GlidArc, after which the discharge is stopped.
A reactor for catalytic oxygenation conversion of carbonaceous combustible matter using a partial oxidation (POX) method into synthesis gas, characterized by comprising an outer vessel (1) and an inner vessel (3) placed inside it with a perforated diaphragm (4), in which two consecutive POX catalysts (10) are arranged in layers, supported on carriers. The first catalyst layer (11) consists of a mixture of nickel and cerium oxides with a weight ratio of Ni/Ce from 0.5 to 1, exhibiting oxidizing properties at temperatures from 1200 to 800° C., while the second catalyst layer (12) consists of metallic nickel or a mixture of nickel and cerium oxides with a weight ratio of Ni/Ce from 1 to 10, demonstrating reduction-recombinatory properties at temperatures from 800 to 300° C. At least two independent temperature sensors (13) are placed in the first catalyst layer (11), and the outer (1) and inner (3) vessels are covered with the same sealed cover (5), in which an inlet (7) for the carbonaceous material and oxygenating agent and electrodes (14) for igniting the GlidArc plasma, initiating and controlling the cold start-up of the reactor are located, while the reactor's outlet is formed by a tube (6) attached to the outer vessel (1).
